fects the cost of shipment of the boards either to the textile mill, orfrom the mill.

to the consumer in bolt form.

By study and experiment I have found that an improved cloth board ofthis type can be made with a frame of materials of the class broadlyreferred to as paper instead of wood, with a great saving in cost ofmaterial while possessing substantially as much strength or morestrength than wooden frames, unless the latteriare very carefully made.Incarrying. out the invention as exemplified in the specific structurechosen for illustration, not only is the completed cloth boardsubstantially hollow in the sense above mentioned, but the individualmembers constituting the frame are themselves hollow or tubular in orderto provide great strength I and rigidity, with very light weight and aminimum' amount of material and therefore at very low cost. The materialused ispreferably a cheap grade of paper stock or pulp and it may bespecifically of the classes know as strawboard or pulpboard, suitablyformed and secured together asdescribed hereafter. While this economicalmaterial has not a high finish or especially attractive appearance,these items are insignificant because the frame parts are, in preferredcases, entirely. concealed by'cover or envelope'materials.

The frame structure is also devised so that, without regard to thespecific material employed, it is very strong and rigid in proportion tothe weight or cross sectional area of themembers, and especially the endmembers have portions which overlap the ends vof the side members toresist inward dis placement of the end members and to provide smooth,flat outer end faces of the frame which have an area equal to the fullwidth and thickness of the frame and so. i

provide proper bases to receive and maintain necessary end labels inproper condition during the life of the'frame and cloth boa-rd or of thefabric bolt in which the board is use'das a core. Other structuralfeatures of the frameare fully explained in the detail description. l pv The characteristics and advantages of the invention" are furthersufficiently. described inconnection with a detail description of theaccompanying drawing," which shows certain exemplifying embodiments ofthe invention; After considering these, persons skilled in the art willunderstand that many variations maybe made within theprinciples of theinvention, and I contemplate the employment of any structures that areproperly within the scope of the appended claims. vlt ig. 1 is aperspective view of. a cloth board embodying the invention in one form.Fig. 2is a perspective view o'f the frame with a part broken away, inposition upon a sheet of envelope or cover material which isready to :befolded and secured upon the frame.

Fig. 3 is a section at 3-3,Fig. 1.

Figs. 4 and 5 are perspective views of 7 frame details.

The frame comprises the longitudinalor slde members S, end members E,and preferably one or more transverse members,

which are conveniently called braces, B.

Each of the frame members for reasons above stated, is preferably hollowor tubular, butthe forms of various members preferably differ. Thus, theside membersQS are more desirably of cylindrical form and thetransversemembers, including E and B, are desirably of polygonal orrectangular cross-section. I

The side members S 'may conveniently consist of ordinary commercialtubing formed from spirally rolled strips of straw- -board or othersufficiently cheap material of the same: general class. These tubes are,

use avoids manufacturing cost other thanv cutting to proper lengths.They are'also available in the general marketand their this structureprovides desirable fiat outer faces for contact with the envelopematerial, but because polygonal members are more easilyshaped for securefastening to the cylindrical side members, as will appear.

The braces 13 may each be formed from a single sheet 1 of fibrous sheetmaterial of suitable grade with due regard to economy, and ofsubstantial thickness and stiffness for the necessary structuralstrength. Specifically, in one preferred form, I have made thetransverse members, including braces B of a fairly cheap grade of pulpboard. The blank isscored or creased along the lines 2 to facilitatebending, and is then bent into rectangular tubular form, as sufficientlyshown in Fig. 2. One'longitudinal portion or flap, such as 3, overlapsanother, such as 4:, and these are adhesively secured together to form astrong'and unitary tubular frame member. Before or after the blank isfolded and secured in tubular form, part-circular cuts are made in itsends, producing the arcuate formations 5, which are so arranged thatwhen the blank is folded into tube form these curvatures are at oppositesides of the tube ends, and the entire tube end is thus shaped toaccurately fit the curvature of the sine member, against which it isplaced and adhesively secured in a manner which is obvious in Fig. 2. Adetail ofadvantage con-' sists in so arranging the blank portions havingthe cuts 5, that they are preferably made in the overlapping members 3and 4; as well as one of the other blank portions 6. In this way thegreatest area of'end surfaces of these members is provided for adhesiveattachment to the side members.

The end frame members E may desirably be made in two or more parts,securely fastened together as explained below. One principal part 10 ofeach end member may desirably be substantially identical With the crossbraces previously described, although evidently dimensions may be variedas neces sary or desirable. Against an outer face of this portion 10 islaid and adhesively secured another main outer portion 11 (Fig. 5) whichmay itself be composed of a plurality of layers or plies 12 of fibroussheet material, usually pulp board of the same grade and thickness asthe blanks 1. Of course in some cases a single ply outer member 11 maybe used, but a multiple structure is generally preferred, in order togive great stiffness and strength to the board ends. Usually the outermembers 11 are glued to the sides of-the tubular members 10 whichconsist of the overuapped blank portions 3 and 4 in order to provide thegreatest available strength and stiffness at points as near as possibleto the board ends.

The members 11 project beyond the ends of members 10 and overlap theends of the side members, and are formed with rounded ends 18 to conformto adjacent outer surface contours of the side members. In brief theseouter membersll ae dimensioned in conformity with the end outline of thecompleted board, as easily understood in Figs. 1 and 2, and the roundedends 13, of course, conform to the curvature of the side tubes whichthey overlap. A complete end member consisting of portions 10 and 11 maybe secured together and used as a unit in building up the framestructure, or the separate members may be. positioned and securedindependently.

When cloth boards are placed in winding machines to wind fabric uponthem the chucks of the windingmachine impose heavy end pressure on theboard ends tending to displace the end members inwardly unless the endmembers are properly designed and securely held against suchdisplacement. In the present structure the formation of the end members1011 with end portions fully overlapping the ends of the side members Sprovides for the transfer of this winding chuck pressure directly to theside members without possibility of displacing the end members inwardly.Shoulders of substantial area are also formed at the ends of the endmembers adjacent the portions thereof which overlap the ends of the sidemembers. These shoulders engage and conform to the inner contours of theside members and provide ample contact and bracing effect to resistangular distortion of the frame. Also the formation of the end memberswith their end portions overlapping the ends of the side members,provides smooth, flat outer faces which cover the full areas of theboard ends without any joint or other interruption, and these areas aretherefore admirably adapted for the proper reception and retcntion ofthe necessary end or finishing labels in proper condition during thelife of the cloth board or the fabric bolt in which it is used as acore. The ends of the overlapping portions of the end faces are alsoconformed in accordance with the outer edge contours of the side membersso that the board edges from end to end are smooth and straight, andprovide an uninterrupted smoothly roundedsurface for the fabric, edgemargins of which overlap the ends of the board end pieces 11. In thefinished bolt the end labels applied to the outer faces of the endmembers 11 are practically fiush'with the aligned edges of the fabricwound upon the board.

For the sake of attractive appearance and to form a smooth anduninterrupted outer surface upon which fabrics of any description may bewound without injury, the frame is usually covered. Any suitable fabricor fibrous sheet material may be used for this purpose, but preferablythe cover or envelope 0, Figs. 1 and 2, consists of fibroussheetmaterial of substantial thickness and strength for the purpose inView, although usually not nearly so thick as the sheet materialcomposing the frame members. In brief, a suitable envelope material is afairly goodgrade of'wrapping paper, which need not be very heavy orexpensive, since the main purpose of the envelop is to cover and sealthe frame and provide an unbroken surface in' the completed board;although, of course, where the cover material has any very substantialtensile strength it serves tomaterially reinforce and strengthen thecompleted structure.

The envelope may be glued before or during its application to the frame,and for convenience in factory production methods, one entire surface ofthe sheet may be glued as indicated by stippling in Fig. 2. This isespecially convenient Where automatic or partially automatic gluingmachines are provided, and which, in many cases, are arranged to glueentire sheet surfaces and ad Vance them to a point of utilization. Whenthe sheets are thus glued over their entire surfaces, that operation, ofcourse, automatically provides for the adhesion of the sheets to framemembers wherever it overlies them, and also for securing the overlappedlongitudinal sheet margin, such as 15. When so glued, the adhesive tendsto materially reinforce and strengthen the sheet at points where it isnot in contact with frame members.

Otherwise, glue may be applied only to certain areas of the envelopethat are'to be brought in contact with frame members, in addition to theflap portion 15. Thus glue may, when desired, be applied to longitudinalareas corresponding to the areas of contact with the side frame membersS. The envelope is applied and folded about the frame in an obvious Wayand secured by pressure, care being taken to stretch the sheet smoothlyand tightly.

Usually the main envelope sheet is only long enough to cover the sidesand longitudinal edges of the frame. In such cases, preferably, endcoverings 20 are provided, Which are usually in the form of sheets ofpaper of a sufiiciently high grade to provide an attractive finish andappearance. These paper sheets are glued and applied in a mannersufficiently indicated in the drawing, so as to cover end marginalportions of the sides and longitudinal edges of the envelope and theouter faces of the end frame members 11. These end areas 21 may, ifdesired, be imprinted with any suitable indicia, such as advertisingmatter or grade marks to identify the fabric in some way, or else theend cover sheets may be entirely plain, and separate end labels may beapplied by the textile manufacturers.

The complete article, as shown in Fig. 1,

is very stiff and rigid, being resistant to ordinary bending strainsinany direction, and also to twisting'strains. It is'amply strong toproperlyhold and support any fabric which it. is desired to wind uponit,

and as strong or stronger than the average I wood frame'board. It'alsohas an attractive surface appearance or finish, and theenvelope or coveris practically perfectly smooth and affords a proper surface for contactwith any fabric.
